Allows for hypothetical calculation of grades for assignments in HISD's gradespeed portal.

Allows for hypothetical calculation of grades for assignments in HISD's GradeSpeed portal. Open the normal GradeSpeed portal, then click the button in the top right corner saying "Open what-if grades". Once on the page, click on any of the class averages to view individual assignments as normal. Next to each grade spot, there should be a write button that allows you to change the grade and update the averages accordingly. This allows for you to preview what certain grades would do to your overall average. This takes grade weighting into account.

Version 0.9 - More refactoring Version 1.0 - Added delete feature and fixed some calculation bugs Version 1.1 - Properly rounded final average instead of forcing it to round up Version 1.2 - Added feature to add final exam grades to change semester averages Version 1.3 - Fixed broken link trigger.
